查询词典 equivalent capacitance

From the basic principles of the AC machine,using the equivalent analysis method, a series of the equations、vector diagram、equivalent circuits of BDFM were obtained, which is the foundation of the analysis and control of the BDFM wind power generation system. The variable structure control was first used to the active and reactive power decoupling control of the BDFM.

Seed cotton yield of 7.9 t/ha and 7.2 t/ha have been achieved under experimental conditions and under on-farm trials in farmers' fields (Bhatti, 1. M, et al, 1981). During 1991 at a private farm of Mr. Sadiq Akbar Bokhari in Multan area of Punjab, average yields of 3.5 t/ha equivalent to 1.2 t lint/ha from an area of 80 ha and 4.5 t/ha equivalent to 1.5 t lint/ha from an area of 20 ha were obtained. Recommended agronomic practices including the application of weedicide, pesticides, fertilizers (125-50-50 N-P2O5-K2O kg/ha) besides planting of cotton on ridges were followed. Crop was planted between 5-30 June and harvested between November and following February. Wheat was planted on 4 ha in standing cotton in the end of November and produced 2.8t/ha yield.

However, in designing the beamless slabs with equivalent frame method, the stress is an average values along the depth of section, which varies with the normal service state. Compared with the results by finite element method, the results gained by equivalent frame method cannot satisfy the requirement under the normal service state. Therefore, the tendons of beamless slabs should be designed and arranged based on the results of FEM taking account into vertical load and prestressed load.

本文通过分析，认为采用等代框架法进行无梁板设计时，其内力是基于截面平均的结果，在正常使用状态与实际受力状态有很大的不同，通过对比等代框架法和有限元计算的正常使用极限状态应力可知，按等代框架法设计的预应力布置并不能保证其正常使用极限状态的要求，据此提出了应根据无梁板在竖向荷载和预应力共同作用下弹性有限元分析结果进行预应力筋布置的建议。
